i getting data 1 of following names, adam, bob, cam, dan, earl, or fred. i want pairs operate on each other. right have string: string list="adam-bob;cam-dan;earl-fred"; then split them via semicolon string[] splitlist=list.split(';'); now have array of pairs so adam-bob cam-dan earl-fred [0] [1] [2] ideally, perform operation on each of them, instead find can following: split via ',' foreach (string s in splitlist) { string firstperson=splitlist[0]; string secondperson=splitlilst[1]; if (udpoutputdata.contains(firstperson)==true) { //record data string firstperson } if (udpoutputdata.contains(seoncdperson)==true) { //record data string secondperson } //if have data firstperson , secondperson, perform operation , give me output } unfortunately, if name adam, followed cam, operations disorganized. perhaps need automatically create string each name? or there eloquent way of operating data on first array... you array

another regex question, yes, context implementation within grunt process, known set of files iterate , in files known combinations of script tags. there 0 chance of user interference, , target files not change on time. here combinations want catch in single regex: <script>*</script> <script type="text/javascript">*</script> edit: above combo should exclude: <script src=""></script> <script src="" type="text/javascript"></script> <script src=""></script> <script src="" type="text/javascript"></script> and need second regex catch following: <!--[if lt ie 9]><script>*</script><![endif]--> and third regex catch following: <!--[if lte ie 9]><script>*</script><![endif]--> please don't combine regexes, need different outcomes each. for reference, i've worked way through answ

i need merge 2 large csv files (approximately 40 million data elements in each ~500mb) common row or column labels, can specified user. example, if dataset1.csv contained: patient_id x1 x2 x3 pi1 1 2 3 pi3 4 5 6 and dataset2.csv contained: patient_id y1 y2 y3 pi0 0 0 0 pi1 11 12 13 pi2 99 98 97 pi3 14 15 16 the user specify merge these 2 files row labels (the patient ids) , resulting output.csv be: patient_id x1 x2 x3 y1 y2 y3 pi1 1 2 3 11 12 13 pi3 4 5 6 14 15 16 since combine information patient ids common (intersection) both input files. strategy problem create hashmap, row or column labels merged (in case row labels, patient ids) keys , data patient id stored arraylist value. create hashmap each input data file , merge values based on similar keys. represent data 2-d arraylist of t
